To all whom it may concern.-

Be it known that I, Gnonsn H. Lovs, a citizen of the United States,residing at lt ueblo in the county of Pueblo and State of Colorado, haveinvented certain new and useful Improvements in Tooth-Brushes, of whichthe following is aspecification.

This invention relates to an improved tooth brush and the principalobject of the invention is to'provide improved means for rotatablymounting a tooth brush and to further provide improved means forrotating the brush so that the brush may be caused to rapidly rotatefirst in one direction and then. in the opposite direction, theactuating lever for the shaft of the brush being carried by the handleof the brush and moved through the medium of the thumb.

Another object of the invention is to so construct the brush that with asmall amount of efiort the brush can be caused to rotate very rapidlyand thus the teeth thoroughly cleansed.

Another object of the invention is to so construct the brush that itwill comprise a comparatively few number of parts strongly connected toprovide a durable, but at-the same time light brush, easy to handle.

. This invention is illustrated in the accompanying drawings whereinFigure 1 is a view showing the brush in top plan; Fig. 2 is a Viewshowing the brush in side elevation; Fig. 3 is a transverse sectionalview taken along the line 33 of Fig. 1.

The handle 10 of this brush is provided with a cut out forming a passagewayll and is further provided with a bridge or guiding bracket-12extending across the passage way 11 to guide the movement of the rackbar 13 carried by the actuating lever 14 and braced by means oi the rodor bracing arm. 15. This actuating lever is pivotally con nected withthe handle '10 means of the thumb screw 16 and is yieldably held in thenormal position by means of the spring 17 so that when pressure isreleascch it will he returned to the normal position, a linger 18 beingprovided to prevent the spring It?" from moving the rack bar 13entirely'out of the passage way 11. An eye 19 is provided for the thumbto fit into so that this lever can be easily moved by means of thethumb. with the fingers passing through the eyes 20.

lhe brush housing 21 is provided with a collar or neck 22 which fitsupon the end of. the handle 10 and is secured in place by means of setscrews 23. The shaft 2% ofthe brush 25 passes through the brush housing21 and the end of the handle 10 and. has each end formed into a pivotpin 26, which pivot pin fits into bearings 27 and 28. formed in theouter end of the brush housing 21 and in the end of the handle 10. Agear pinion 29 is rigidly mounted upon the brush-shaft" within thepassage way 11 and is engaged".- by the teeth of the rack bar 13 so that58 K the rack bar is moved with the lever the:

brush shaft will be rotated according to the with the fingers passingthrough eyes 20 and the thumb passingthrough 'eye 19, thesictuating'lever 14 can be moved toward. the handle and the brush willbe rotated in one direction. Upon-releasing the pressure upon the leverthe spring 17 willreturn the lever to the normal position shown in Fig.1 and the brush will be rotated in'the 'oppositu' 50 direction. When itis desired to clean the brush, or replace the same with a new one, thebrush housing can be removed from the handle after releasin shaft easilyremove case it is desired to replace the brush, or if it is only desiredto thoroughly clean the same, the brush can be cleaned and the brushhousing then put back in place. I have therefore provided a tooth brushwhich 90 will be very easy to use and which will he so constructed thatit can be easily cleaned and thus kept sanitary.
